Gravity surveys have a huge range of applications, indicating density variations in the subsurface and identifying man-made structures, local changes of rock type or even deep-seated structures at the crust/mantle boundary. This important one-stop book combines an introductory manual of practical procedures with a full explanation of analysis techniques, enabling students, geophysicists, geologists and engineers to understand the methodology, applications and limitations of a gravity survey. Filled with examples from a wide variety of acquisition problems, the book instructs students in avoiding common mistakes and misconceptions. It explores the increasing near-surface geophysical applications being opened up by improvements in instrumentation and provides more advance-level material as a useful introduction to potential theory. This is a key text for graduate students of geophysics and for professionals using gravity surveys, from civil engineers and archaeologists to oil and mineral prospectors and geophysicists seeking to learn more about the Earth´s deep interior.

A one-stop resource providing a manual for data acquisition and methods for analyzing the data
Textbook treatments of gravity methods are usually restricted to chapters in more general geophysics books; this distinctive book provides important detail and practical assistance
Together the authors have acquired over 40,000 individual gravity measurement points in surveys for environmental, engineering and regional tectonic applications, providing truly expert and in-depth insight
